20nf capacitor (1) 




16vac power source (1) 



Step 1 — Wireless Power Transfer 




• The first thing is to make the big 
coil. You can do this by putting four 
nails into a board and wrapping the 
copper wire around them.

Step 2 




• Then you have to make the smaller 
coil. It has to be about half the size 
of the bigger one. You need to put 
an LED/bulb and a capacitor on the 
output. I put 2 because I didn't have 
one that had the right value. You 
could also put a bridge rectifier on 
it to turn the AC into DC. 



Step 3 




• Connect the power to the big coil 
and put the small one in the middle 
and the LED should light up.

Step 4 




• I tested different gauge wire and 
the maximum efficiently I got was 
42.2%.
